PROCESS FOR THE PRODUCTION OF INSULATIONS AGAINST LOSS OF HEAT.

1 0 aZZ whom it may canoe m:

Be it known that I, Prrrmrr GELIUS, a citizen of the German Republic,residing at Munich, Bavaria, Germany, have invented certain new anduseful improvements in Processes for the Production of lnsulationsAgainst Loss of Heat, of which the following is a specification.

This invention relates to a process for the production of insulationsagainst loss of heat for accumulators for heat, for conduits, reservoirsand the like. The insulation is obtained with the aid of layers of woodshavings, straw, peat or other organic or vegetable substances adaptedto be carbonized which are coated with clay, cement or other convenientmaterials, said coating being applied before, during or after themounting in place of said insulatingdayers and serving for protectingthe insulation.

By chemical binding, drying, heating or any other convenient treatmentthe envelope or mortar is transformed from the moist and soft state intothe dry and solid state.

The layers enclosed in the envelope of mortar consist for instance oftissues, ropes or strings or wood shavings, wood fibres, straw, peat orother similar materials or substances which possess, owing to theirstructure a nigh insulating capability and which are adapted to becarbonized, in order to increase essentially the degree of insulatingcapability. The complete carbonization ot the insulating material isaccelerated or produced and completed either mechanically, for instanceby direct burning with the aid of a blow-pipe-fiame or the like or bymeans of incandescent bodies, chemically by caustic process, or finallyelectrically, in whlch case thin wires would be embedded in the insulating material, said wires being Wound so that they form electricresistances. When the ends of said wires are enclosed in an electriccircuit the insulating materials are carbonized. The carbonizedsubstances are properly held by the protecting envelope of mortar.

Application filed September 17, 1921. Serial No. 501,448.

According to the degree of the insulating etl'ects which have to beproduced the insulation can consist of one or of several layers ofinsulating material. it several layers are used all these layers can becarbonized or only one or several of the same so that heat whichradiates from the conduits, reservoirs or the like encounters firsteither the carbonized insulating materials which have a greaterinsulating action than the insulating substances in natural state, orthe uncarbonized insulating materials, in which case the layer or layersof carbonized material are farther distant from said objects.

I claim 1. An improved process for the production of insulations againstloss of heat con sisting in covering the insulating mantle made fromropes of wood shavings with an envelope of mortar, the. insulatingcapability of said wood shavings being increased by dry distillation.

2. An improved process for the produc tion of insulations against lossof heat consisting in covering the insulating mantle made from ropes ofwood shavings with an envelope of mortar, the insulating capability ofsaid wood shavings being increased by carbonization of the materialefiected with the aid of electric current.

3. An improved method for the production of insulations against loss ofheat consisting in covering the objects to be insulated with a layer ofcombustible insulating material, e. g. wood shavings, straw, peat andlike substances in convenient shape, in coating said layer with a mantleof mortar and in carbonizing said insulating material in a convenientmanner.

In testimony whereof I affix my signature in presence of two witnesses.
